HOLDER FOR YARN PACKAGES.

Application led February 11, 1922. Serial No. 535,950.

To all whom t may concern:

Be it known that I,4W1LLIAM D. HARTS- HoRNE, a citizen of the UnitedStates, residing at Methuen, in the county of Essex and State ofMassachusetts, have invented certain new and useful Improvements vinHolders for Yarn Packages, of which the followin is a specification.

his invention is for use 'in the spinning, setting and weaving of yarn,more particularly of worsted or cotton yarn used for filling.

In the process of spinning of yarn for weaving purposes, whether it isto be used for warp or filling, it is necessa I to give it a certainamount of twist in or er to assure evenness, roundness and strength. Theamount of twist required depends largely upon the quality or characterof the cloth o which the yarn is toh become a part. In order to hold thefibres in their position and retain this twist, it is necessary tosubject the yarnto some setting process which consists of introducing aproper amount of moisture, either hot or cold.

To accomplish this, the yarn on bobbins was formerly stored away andkept in a cool damp room, usually in a cellar, for a long period oruntil it had lost its tendency to kink or loo and had absorbed the reuired amount o moisture. This plan, alt ough effective was,nevertheless, slow and expensive because it kept tied up in the processa large amount of yarn and a great many bobbins.

The general practice at the present time consists of thoroughly steamingthe yarn by allowing it to remain in or to pass through rooms or chestsfilled with hot steam or vapor which gives it the required moisture vand accomplishes the desired setting effect in a relatively short time.

As is to be expected, however, it is found that these conditions of heatand moisture to which the yarn is subjected have a damaging effect onpaper tubes or wooden bobbins on which the yarn is wound, whetheroriginally spun thereon or subsequently wound by some so-called quillingoperation. The paper tubes are made practically worthless for furtheruse, while the wooden bobbins are softened and swelled, or twisted outof shape, and their life is materially shortened. Further than this, thetubes or bobbins in general use are solid, and for this reason themoisture has to penetrate the lentire mass of yarn from the outside.

I am aware that perforated metal cops and bobbins have been used fordyeing and for other purposes, and I do not claim broadly the idea ofsuch a perforated metal cop or bobbin. I do claim, however, to be thefirst to provide a light, inexpensive barrel or tube, preferably, rolledfrom perforated sheet metal, having a member by which it can be firmlyattached to and detached from a suitable head for the purpose of makingit available for use in a loom shuttle.

The principal feature of my present idea is the provision in a holderfor a yarn package of a barrel preferably of moistureresisting metalupon which, without its head, the yarn can be spun or twisted and whichcan then, with others of a similar kind, be treated in a steam chest orbox or any suitable steamin or boiling arran ement to set the yarn, incombination with a readily attachable and detachable head to bethereafter attached, for weaving or other purposes.

As it is necessary that this barrel should be capable of being held on aspindle or other device in a spinning or twisting frame, I prefer tomake it of more or less elastic sheet metal so rolled up as to leave alongitudinal split. This allows enough spring to hold the barrel implace. Besldes this, not only to permit the steam to get inside the yarnpackage but to prei vent theyarn from slipping, I perforate it with aplurality of holes.

Various types of catches between the barrel and the head can be used,but it is desirable that the whole structure should be light in weightand should have no projecting parts which might catch the yarn or injurethe operators hands.

I claim to be the first to conceive the idea of a straight barrel ofperforated metal or other suitable material without a head to be used inthe process of spinning, twisting, or quilling and steaming, combinedwith a head which may be attached only before, during, and after thetime when the bobbin is being used for weaving filling in a loom orother particular process.

I claim the use of a metal barrel with a head which may be of wood orany material which is readily attachable to and detachable from thebarrel,

l also claim to be the first to provide a barrel with a member by whichit can be attached to and detached from a head.

lf show my preferred type of yarn holder in Figs. 1, 2, 3, 4, 5, 8, 9.The barrel B is formedof a sheet of metal, preferably, such asduralumin, which is not affected by steam or boiling water and will notstain the yarn. Such sheet is perforated with the holes 31 and may havethe bead 13 proximate what is to be its tip expanded therefrom, and thebead 15 expanded therefrom near what is to be its base, either before orafter it is rolled up into a tube or barrel with its opposite edges 10,1() substantially brought together. Preferably, a flat sheet of metal ispunched with the holes 31 and at the same time the beads 13 and 15 areexpressed, after which it is rolled up on a mandrel with its edgestouching.

Beads 13 and 15 may be expanded before or after rolling. Bead 13 isproximate the tip and serves to guide the yarn from the yarn package,such as L, smoothly over the tip 12. rFhis tip 12 is likely to becomemore or less roughened in the rough usage of the factory, but bead 13keeps the yarn away therefrom and also protects the hands of theoperator.

The bead 15 is a sufficient distance away from the base 14 of the barrelso that when assembled with the head it will form therewith one of twofirm holding lines of contact, from without or within the barrel.

After the barrel B is made, it may for the purpose of spinning be placedupon a steel spindle for ring spinning or twisting or forced over thewooden shank 8 of a wooden bobbin M carried by the tube and whirl 7 inthe case of cap spinning or twisting. rlhe barrels split formationallows it to be forced over bobbin M or over a guide button on the steelspindle whereby it is held firmly in position during. the spinning ortwisting.

'llhe yarn 6 is spun or twisted thereon forming the yarn package L whichmay either be what is known as a warp wind or a simple cop like fillingwind.

1n Fig. 2, lf show this yarn package, including barrel B and yarn L,removed from the spinning frame and placed in a steam chest or othermoistening device, which may be even a damp cellar. The arrows indicatehow the moisture or steam passes in through the holes 31 to the insideof the package.

Figs. 3, 4 and 5 show details of the preferred form of head H. rllhismay be made of sheet metal, which may be of moisture resisting materialor otherwise, as ordinarily this head does not come in contact with hotsteam. 1t is formed with a round base 20 through which is, preferably, apassage 2l for a spindle in case it is desired to usethis in a shuttlehaving a spindle. necessary, however, in a shuttle for an automatic loomwhich has jaws, such as those shown at N in Fig. 9, with grooves 27..

For this type of shuttle, l prefer to use elastic clamp members 22, 22,22, 22, separated by spaces 24, 24, 24, 24, each having expandedtherefrom the three beads 23, 23. 23 adapted to engage grooves 27, 27,27- of the jaws N.

Preferably, the upper edge of each clamp 22 at 25 is rolled over inposition so that it will permit bead 15 of barrel B to just pass insideand will engage it firmly.

'll'he base bead 15serves as an attaching member for the barrel, and theclamp members 22, 22, 22, 22 serve as elastic attaching means for thehead, cooperating therewith. The distance from barrel base 14 to basebead 15 should be such that when base 14 rests on head base 20, therolled-over edges 25 of clamps 22, 22 pressing against the outer edge ofbead 15 will hold bases 14 and 2O firmly together.

1s the head H need not be used in spinning nor in setting, it can beattached to the barrel by unskilled labor just before beingput in themagazine of the loom, and after it is forced into the shuttle betweenthe jaws N these jaws force the clamp members 22 against the barrel andagainst bead 15 so that Utl rFhis is not the two parts are irmlyandelastically held in position with no danger of rattling out duringWeaving.

In Figs. 6, 7 and 14, I show a barrel A which is split at- 30,perforated at 31,- has the tip 32 and bead 33 proximate thereto, but atthe other end has a series of wings 35 adapted to engage the interiorthreads 42 on a solid head C. This head C has an end throu h which theremay be-a spindle hole 41 and t e exterior steel rlngs 43, 43, 43 for usein an vautomatic loom. The pad P is shown between an end of the barreland the interior of the head to prevent rattling and to hold the partsirmly in position. The split construction of the barrel also helps inthis respect.

Pad P may be of washer form with a hole corresponding to 41, preferablyof more or less elastic material such as felt or rubber and of athickness so that when the barrel A is in position the parts will all befirmly held together. A pad such as P can be used with the type ofbarrel B and head H if necessary, but ordinarily the elasticity of the lclamps is suiicient.

In Figs. 11 and 12, I show still another modification. in which thebarrel G is per- Jorated at 61 but is not made of sheet metal and is notsplit, while the bead 63 is at the tip 62 instead of a short distancetherefrom. There may be another bead 65 to prevent the yarn slippingdown, but this is not necessary 1n all cases.

The head F is shown as having a spindle hole 51 and interior threads 52which engage exterior threads 66 on the barrel. The pad P is omitted inthe drawing but can be used.

In Fig. 14, I show a barrel A similar` to that shown in Figs. 6 and 7,which is perforated and split and has a bead 33 near the l tip togetherwith wings 35 near the other end, in combination with a head T.

Head T is shown as made of solid metal with an outer end 70 throughwhich is a hole 76 and about which are themetal rings 73, 73, 73 to fitin the jaws of the shuttle. On the inside, it is threaded at 72 toengage the wings 35 on barrel A. It also has a guiding and supportingtube 74 which is fixed in the hole 76 and extends u to a point insidebarrel A, its end bein en arged at 75 to form an annular support or theinterior of the bar- A pad P is shown outside tube 74 resting upon thebarrel recess in head T between the end of barrel A and the end of headT. This pad forms part of the elastic attaching means including threads72 and vwings 35 between the barrel and head.

While I prefer the various types hereinbefore described, I may use acompound bobbin, such as shown in Fig. 15, in which the barrel R isneither perforated nor split-and is not made of sheet metal but ismadeof heavier stock which can be rounded at the tip 66 instead ofhaving a bead thereat. I do not conne myself to the use of a metalbarrel, however.

This barrel R of tubular form made of moisture-resisting material isshown as combined with a head S tmade of wood or similar material havinga butt 67 and a shank 68 which is slightly tapered so that the barrel Rcan be driven on to it and will be thereby held in place. In this case,the attaching member of the barrel may be regarded as the inner bore 69,and the attaching means from the head cooperating therewith as the shank68.

In Fig. 16, I-show a barrel B and a head H similar to those shown inFig. 8, and instead of a washer such as P which goes under the end 14 ofbarrel B, I show a washer V, which may be of any material, set in on thebottom 20 of head H in such position that the end 14 of barrel B willslip inside of it thereby assisting the rim 25 to hold the parts morefirmly together.

In Fig'. 17, I show a similar barrel B and a head 'I similar in allrespects to I-I except that instead of the washer B I press inward anannular bead 70 in such position as to engage the end 14 of barrel B andto hold it rigidly in position together with rim 25.

I claim: l

The combination in a holder for a yarn package of a barrel of tubularform made of moisture resisting sheet metal split long-itudinally andhaving perforations, together with an expanded annular bead proximateits tip and an expanded annular bead near its base; with a head havingan end which' engages the base of the barrel and elastic clamp membersextending therefrom, each having a rim extending over said annular basebead, and expressed annular beads for engagement with the jaws of ashuttle.
